Shooting indoors, with other people banging away, easy to miss a squib if one isn't watching for it.
Proly thought he just had a gun issue, not ammo issue.
Autos............people should be on the watch, suspect squib at any cycle failure or odd sound.
Revolver guys doing speed drills, usually shove em out with the next one (and ring the bbl) LOL
Worked a shop w indoor range.
Brass rod got a workout.
Some folks had rather catastrophic failures.
No RO on range, so couldn't babysit.
For the sake of argument....you all know I love to argue.....how would a squib be a gun issue? Another bullet stuck in the bore
To me if it goes bang, and the tube thingy is not plugged up with stuffs then the boolet should come out....
All kidding aside, I think with a lot of this bulk stuff what happened between the factory and our grubby little paws has a great deal to do with it.
